Description
Technical field
The present invention relates to a kind of rock gas recovering device that is applied on the natural gas equipment.
Background technique
Along with the quickening of expanding economy and process of industrialization, China is more and more to the demand of the energy.Rock gas becomes the important energy source that drives automobile gradually as a kind of eco-friendly power source.Rock gas is as non-renewable energy resources, along with large-scale exploration and exploitation are also fewer and feweri.At some big and medium-sized cities even county town, rock gas has become the main energy sources, automobile of bus, taxi, short-distance small-sized freight in the aerating process, when air filling gun filled it up with gas for the automobile gas tank, seldom a part of rock gas residual in the air filling gun will be discharged to atmosphere again and again.Though it is very little to be discharged the amount of rock gas of waste when aerating each time, because automobile quantity is very huge, the amount that adds up the rock gas that is wasted is still very considerable, and a large amount of dischargings is also very important to the pollution that atmosphere causes.
Summary of the invention
For reducing gas station rock gas waste and to the pollution of atmosphere in the refueling process, the invention provides a kind of can be to the residual device that reclaims to the rock gas of atmosphere side by side in the air filling gun.
For achieving the above object, rock gas recovering device of the present invention adopts following technological scheme:
This recovering device is mainly by air filling gun, recovery tube, gas holder, the gas holder connecting tube, reduction valve, reclaim pneumatic tube, air valve is formed, two gas holder of design and installation in the filling machine housing, gas holder is the double-layer barrel structure, skin is the hard cylindrical shell, internal layer is the elastic caoutchouc tube, reduction valve of hard cylinder top design at each gas holder, hard cylindrical shell bottom is closely fixing with the rubber tube bottom, between hard tube top and the rubber tube top, between hard tube sidewall and the rubber tube sidewall certain distance is arranged, the rubber tube of two gas holder is communicated with the gas holder connecting tube.Recovery tube one end is connected with relief opening on the air filling gun, and the other end is connected with a gas holder.The internal layer elastic caoutchouc tube bottom design of the gas holder that is connected with recovery tube has valve lever movable up and down, design has two rubber air valves on the valve lever, the corresponding recovery tube port of rubber air valve, the corresponding gas holder connecting tube of another rubber air valve port.One is reclaimed pneumatic tube one end and is connected with the filling machine suction tude, and the other end is connected with unidirectional gas outlet valve on the gas holder.
In addition, rock gas recovering device of the present invention can also be taked filling machine, gas holder split design, and the gas holder that is about to design side by side is installed in outside the filling machine housing.
The working principle of rock gas recovering device of the present invention is:
Utilize principle of negative pressure, when giving the aerating of automobile gas cylinder, filling machine will find time to form vacuum state with the gas in reclaiming second gas holder that pneumatic tube links to each other, after adding gas, the rock gas that the maimed person stays in the aerating gun barrel enters in the rubber tube of first gas holder internal layer by recovery tube, rubber air valve.Rock gas runs up to a certain degree and forms certain pressure the rubber air valve is backed down in the rubber tube of first gas holder, enters in the rubber tube of second gas holder internal layer by the gas holder connecting tube then to store.When being refueling once more, work along with the press of installing on the filling machine, the interior rock gas of rubber tube that is stored in second gas holder just enters the press suction tude by unidirectional gas outlet valve, recovery pneumatic tube, adds the automobile gas cylinder by air filling gun then after the press pressurization.By work so repeatedly, residual rock gas just is fully utilized in the air filling gun in the aerating process, thereby reaches effects of energy conservation and environmental protection.
Rock gas recovering device of the present invention has characteristics safe in utilization simple in structure, with low cost, easy to operate, can obtain energy-saving and environmental protection effect preferably after installing and using.
